CORK PULLING MACHINE Original Filed Jan. 22, 1931 5, 9 C/QHYL Patented Dec. 5, 1933 UNITED STATES PATENT OFFICE Application January 22, 1931, Serial No. 510,527, and in Sweden January 20, 1930. Renewed March 28, 1933 3 Claims.

The cork-pulling machines commonly used in restaurants and the like are, on the whole, constructed in such a way that the corkscrew is screwed into the cork, the cork is pulled and the screw is screwed out from the cork again. A toand fro-motion is necessary for this operation. t is very diiiicult to provide power operation, for instance electric operation,for said motion. Moreover, on pulling the cork, a quick blow causing noise and crushing of the bottle is produced.

The present invention relates to a cork-pulling machine in which the corkscrew only need rotate in one direction.

An embodiment of the invention is illustrated in the accompanying drawing in which Fig. 1 shows a longitudinal section, Figs. 2, 3 and 4 show sections along the lines II, III and IV.

According to the embcdment shown in Figs. 1-4 the corkscrew 1 is adapted to be pushed upward and downward in a sleeve 2 of a relatively large extension. The corkscrew is held in free position by the spring 7. 3 is an electric motor, and 5 are toothed wheels. 6 is a long spline, 13 is the bottle with the cork 12. 9 is a guide for the head of the bottle, said guide being movable up and down and consisting of a sleeve inwardly covered with elastic material 10 of hard rubber, fibre or the like.

The sleeve 9 and a rod 14 are arranged in such a way relative to a switch 15 which is electrically connected to a motor 3 driving the corkscrew that, when the head of the bottle is pressed against said sleeve 9 and the latter hereby is pushed upwardso far that the point of the corkscrew enters the cork, the current is closed and the motor is started. When the tension of the spring '7 overcomes the resistance of the cork the corkscrew pulls the cork out of the bottle. The sleeve 9 now automatically returns to its initial position, the current being then broken. The corkscrew with the cork are, however, drawn by the spring 7 further upward and on the cork entering the sleeve 2 the side of the cork is cut up by the knife-formed wedge 8. By the wedge 8, which grows in thickness, the cork is split on its way upward, whereafter the cork falls out through the opening 16. In order to additionally facilitate the splitting of the cork, the core-diameter of the thread of the screw is also increased at the end 17 of the thread. In order to decrease the small blow against the sleeve 2 arising at the upward motion of the sleeve 9, an elastic bufler is disposed between the said sleeves (not shown in the drawing), a similar bufier being also provided in order to decrease the blow arising at the downward motion of the sleeve 9.

The invention is not limited to this embodiment. The spring '7 may be dispensed with, and the screw may be fixedly mounted in the position 0 shown in the drawing, in which case the movement of the sleeve 9 should be correspondingly larger.

Instead of one cutting wedge 8 two or several wedges may be provided for, along with a num- 03 her of openings 16 to match.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A cork pulling machine comprising a sleeve, a corkscrew displaced axially in the sleeve, a movable bottle neck guide below the sleeve to aline the cork in the bottle neck with the corkscrew, an electric motor, a gear connection between the motor and corkscrew, a current con- 15 trolling switch for the motor, a rod carried by the guide and movable therewith for closing the switch when the guide is moved upwardly to operate the motor to rotate the corkscrew for engagement with the cork to move the same into the go sleeve.

2. A cork pulling machineas claimed in claim 1, wherein the sleeve has mounted therein a cutting blade to sever the cork when moved by the corkscrew into the sleeve.

, 3. A cork pulling machine comprising a sleeve having a corkscrew therein, a movable bottle neck guide below the sleeve for alining a cork therein with the corkscrew, an electric motor for driving the corkscrew, means carried by the guide for placing the motor in operation to rotate the corkscrew for engagement with the cork when the guide is moved upwardly.
